我在ubuntu中使用deb文件安装了elasticsearch.90.7.
我尝试使用以下命令卸载elasticsearch.90.7：
我尝试使用以下命令卸载elasticsearch.90.7：
sudo apt-get --purge autoremove elasticsearch
然后我下载了elasticsearch-1.6.0.deb来安装elasticsearch 1.6.
当我运行此命令以通过deb文件安装elasticsearch 1.6时：
dpkg -i elasticsearch-1.6.0.deb
它告诉我这个：
Selecting prevIoUsly unselected package elasticsearch. (Reading database ... 89826 files and directories currently installed.) Preparing to unpack elasticsearch-1.6.0.deb ... Creating elasticsearch group... OK Creating elasticsearch user... OK Unpacking elasticsearch (1.6.0) ... Setting up elasticsearch (1.6.0) ... Processing triggers for ureadahead (0.100.0-16) ...
当我使用服务弹性搜索启动elasticsearch时,它开始启动,但是当我运行此命令时：curl http：// localhost：9200
curl: (7) Failed to connect to localhost port 9200: Connection refused
我认为elasticsearch没有正确安装.我想知道我应该怎么做才能正确安装elasticsearch.
(1)删除以前版本的ElasticSearch：
原文链接：/ubuntu/348911.htmlsudo apt-get --purge autoremove elasticsearch
(2)删除ElasticSearch目录：
sudo rm -rf /var/lib/elasticsearch/ sudo rm -rf /etc/elasticsearch
(3)安装ElasticSearch 1.6：
sudo dpkg -i elasticsearch-1.6.0.deb
(4)启动服务：
sudo service elasticsearch start
(5)测试它是否有效：
sudo service elasticsearch status curl -XGET "http://localhost:9200/_cluster/health?pretty=true" curl "localhost:9200/_nodes/settings?pretty=true"
